Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
A vulnerability in the web framework of the Cisco Unified Communications Manager IM and Presence Service software could allow an authenticated, remote attacker to conduct a cross-site scripting (XSS) attack against the user of the web interface of an affected system. The vulnerability is due to insufficient input validation of certain parameters passed to the web server. An attacker could exploit this vulnerability by convincing the user to access a malicious link or by intercepting the user request and injecting certain malicious code. A successful exploit could allow the attacker to execute arbitrary script code in the context of the affected site or allow the attacker to access sensitive browser-based information. Cisco Bug IDs: CSCve25985.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · high confidence

A cross-site scripting vulnerability exists in the web framework of Cisco Unified Communications Manager IM and Presence Service due to insufficient input validation of certain parameters passed to the web server. An authenticated, remote attacker can exploit this by injecting malicious script code through crafted parameters, potentially executing arbitrary code in the context of the affected web interface or accessing sensitive browser-based information.

MitigationApply the vendor patch from Cisco for CSCve25985 to address the input validation vulnerability in the web framework. Users should be cautious of clicking untrusted links while authenticated to the affected system.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Identify if Cisco Unified Communications Manager IM and Presence Service is installed
    Locate the application on the system or check system inventory/Software Center for 'Cisco Unified Communications Manager IM and Presence Service' or 'CUCM IM&P'
    Affected if The product is not installed on the system
  2. Determine the installed version of the IM and Presence Service
    Access the Cisco Unified Communications Manager Administration interface, navigate to About > Version, or use the CLI command 'show version' on the IM&P server
    Affected if The version shown is 11.5 or 12.0 exactly
  3. Confirm the web framework is accessible
    Attempt to access the web management interface via HTTPS on port 8443 or 443, or verify the web service is running using 'utils service list' CLI command
    Affected if The web interface is reachable and responds to HTTP/HTTPS requests
  4. Verify the specific version falls within the affected release range
    Compare your exact build number against the 11.5 and 12.0 release trains - check the 'About' page for the full version string including sub-build numbers
    Affected if The version string begins with 11.5 or 12.0 (e.g., 11.5(1), 12.0(1))

You are affected if Cisco Unified Communications Manager IM and Presence Service version 11.5 or 12.0 is installed and the web management interface is accessible.
